Full Breakdown
5 of the Unified Development Ordinance lists the improvements a developer must install or guarantee before Alamance County grants final plat approval. C. DOT specifications. 5(B) instead sends the developer to that town's own improvement standards. 5(D) separately requires debris, fallen trees, and other obstructions to be cleared from stream channels and drainage ways before the county will sign off on the final plat. Developers of private-road subdivisions face a parallel duty under Appendix L: an erosion control plan for the road corridor is required whenever more than one acre is cleared.
5(A) lets a subdivider guarantee the work with a surety bond, letter of credit, or equivalent instrument worth 125% of the construction cost, payable to Alamance County, and complete the work within eighteen months; an engineer registered in North Carolina must certify the construction and surety amounts. The Planning Department administers plat approval and can withhold it until the erosion and sediment control plan is on file.
Violations & Fines
Skipping the required plan or disturbing land without one violates Article 4 of the UDO. The Planning Director gives the responsible party 30 days to correct the violation before imposing penalties: a civil citation of $500 per violation, with each day of continued violation a separate offense, or criminal prosecution as a Class III misdemeanor under N.C.G.S. § 14-4 carrying a fine up to $500. Staff may also issue a stop-work order halting the land-disturbing activity immediately if it endangers life or property; violating that order is itself a Class 1 misdemeanor.
